项目中用到了 olami sdk把录音或者文字转化为用户可以理解的json字符串。
效果图
重要jS代码：
-
//手指按下时 语音转文字 voiceToChar:function(){ var urls = app.globalData.slikToCharUrl; var voiceFilePath = that.data.filePath; if(voiceFilePath == null){ console.log("[Console log]:File path do not exist!"); wx.showModal({ title: '录音文件不存在', content: '我也不知道哪错了，反正你就再试一次吧！', showCancel: false, confirmText: '确定', confirmColor: '#09BB07', }) return; } var appkey = app.globalData.NLPAppkey; var appsecret = app.globalData.NLPAppSecret; var NLPCusid = app.globalData.NLPCusid; wx.showLoading({ title: '语音识别中...', }) wx.uploadFile({ url: urls, filePath: voiceFilePath, name: 'file', formData: { "appKey": appkey, "appSecret": appsecret, "userId": NLPCusid }, header: { 'content-type': 'multipart/form-data' }, success: function (res) { wx.hideLoading(); var data = JSON.parse(res.data); var seg = JSON.parse(data.result).seg; console.log("[Console log]:Voice to char:" + seg); if(seg == null || seg.length == 0){ wx.showModal({ title: '录音识别失败', content: "我什么都没听到，你再说一遍！", showCancel: false, success: function (res) { } }); return; } that.addChat(seg, 'r'); console.log("[Console log]:Add user voice input to chat list"); that.sendRequest(seg); return; }, fail: function (res) { console.log("[Console log]:Voice upload failed:" + res.errMsg); wx.hideLoading(); wx.showModal({ title: '录音识别失败', content: "请你离WIFI近一点再试一次！", showCancel: false, success: function (res) { } }); } }); },
olami 技术的识别语音代码：
-
// 发送语料到语义平台 sendChat: function (e) { let word = e.detail.value.ask_word ? e.detail.value.ask_word : e.detail.value; console.log("[Console log]:User input:" + word); that.addChat(word, 'r'); console.log("[Console log]:Add user input to chat list"); that.setData({ askWord: '', sendButtDisable: true, }); that.sendRequest(word); }, // 发送请求到语义平台 sendRequest(corpus){ app.NLIRequest(corpus, { 'success': function (res) { if (res.status == "error") { wx.showToast({ title: '返回数据有误！', }) return; } var resjson = JSON.parse(res); var data = JSON.stringify(resjson.data); that.NLIProcess(data); }, 'fail': function (res) { wx.showToast({ title: '请求失败！', }) return; } }); }, // 处理语义 NLIProcess: function(res){ var nlires = JSON.parse(res); var nliArray = nlires.nli; if(nliArray == null || nliArray.length == 0){ wx.showToast({ title: '返回数据有误！', }) return; } var answer = nliArray[0].desc_obj.result; if(answer == null){ wx.showToast({ title: '返回数据有误！', }) return; } console.log("[Console log]:Add answer to chat list..."); that.addChat(answer, 'l'); var dataArray = nliArray[0].data_obj; if(dataArray != null && dataArray.length > 0){ var objType = nliArray[0].type; if(objType == 'selection' && dataArray.length > 1){ that.newsProcess(dataArray); return; } if (objType == 'news' && dataArray.length == 1) { console.log("[Console log]:Add news to chat list..."); var title = dataArray[0].title; var detail = dataArray[0].detail; var news = title + "\n" + detail; that.addChat(news, 'l'); return; } var content = dataArray[0].content; if (content != null && content != answer){ console.log("[Console log]:Add content to chat list..."); that.addChat(content, 'l'); } } return; },
